Beschreibung
Zusammenfassung:	It is disclosed a cable for an overhead power transmission line, the cable comprising: a first optical unit comprising a first metal tube housing at least one an optical fiber suitable for sensing strain, the at least one optical fiber in the first metal tube being a tight buffered optical fiber fixed to an inner surface of the first metal tube; a second optical unit comprising a second metal tube comprising one or more loose optical fibers suitable for sensing temperature; and an armor comprising one or more layers of metal wires. The first optical unit is surrounded by at least one layer of semi-conductive or conductive material electrically contacting the outer surface of the first metal tube.
